Any changes in the PO4 level ?

ZeoFood will not help to reduce NO3, it is just a question of time until the level does decrease slowly.

last Saturday my PO4 was 0.025
I'm thinking to add some aragonite too see if it is going to change anything. I'm also thinking to reduce my bio load.

at the moment I have:
1 yellow tang,
pair of clownfish
1 orange back fairy wrase
2 dispar anthias
5 chromis
1 mandarin fish

I'm thinking to remove chromis and anthias...

I didn't dose xtra and b balance for a couple of weeks but there was no change in nutrients so I'm gonna strart using them again.

Reducing the fish might have a positive impact to NO3, also sand can help but I expect the level does decrease over the time, 5 10 mg is not really a problem, the impact to coral coloration is usually minimal.

You might also check the reactor flow to see if it is to low.

reactor flow is optimal (a bit increased)
Colors looks nice to me and getting better

its been almost 5 months in zeovit so if you expect decrease over the time, that's sounds good to me!

do you think that I have to add zeofood in my schedule or this is not important at all?

Thank u once more!!!

If your corals are doing well and if there is no algae issue you can try to dose 2 drops ZeoFood 2 x weekly if you like to.

yesterday test results:
ΝΟ3: 10+
PO4: 0.06



I suspect siporax removal..

corals color still good to my eyes...

what else can I do to drive my nutrients down to zero? Should I increase flow at the reactor. Currently I run 220l/h
should I add some vodka daily or this is to risky?

I feed my fish every 2 days..

I would recommend you to use a flow of 200 liters per hour through the reactor if you use 0.5 liters of the material for your system with a net water volume of 200 liters.

Give your tank some time now, adjust your skimmer to skim wet, clean the skimmer regular to export as much as possible, vacuum the sand regular while doing water changes.

Continue dosing as follows:

zeobak: 2 drops every other day
Zeostart: 0.2ml x 2 daily
Sponge Power: 2 drops every other day
BioMate: 4 drops every other day
Xtra: 2ml, 2 x weekly
AA: 1 drop weekly
CoralSnow 3ml x 2 times a week pure

Thanx for your answers once more

my net volume is somewhere between 200-230 liters.. fo security reasons I choose to dose for 200 liters

I vacuum my sump every week. I don't have sand. I run the display bare bottom.
My skimmer is the Deltec MCE 600 and it is set to skimmate as wet as possible.. (not producing much skimmate to tell the truth).

I will follow your instructions. the only change is that I'm currently dose bak every day and I don't dose AA,extra and b balance because of the high nutrients.

by the way you didn't include b balance in schedule, do I have to use it for now or not?

If you like to you can dose 2 ml B-Balance 2 x weekly but at the moment it is not really necessary.

update!

today measurs:
Kh: 7
Ca: 435
Mg: 1300
K: 390

No3: 5
PO4: 0.025 (last week was 0.045)

Schedule:
Bak -> 2 drops daily
Start-> 0.2ml two times a day, daily
sponge power-> 2 drops ecvery 2 days
Biomate -> 4 drops every 2 days
Snow -> 3 ml two times a week
extra: 2 ml two times a week

Last week I moved my skimmer (Deltec MCE600) from sump to display tank (its a hang over) and I think it works much better now

I also bought a bag of KZ aragonite and I will keep it in RO water for a week before I use it with daily changes of water.
Will that be enough aragonite? tank is 60cm x 60cm

Does daily addition of bak helps or not to nutrient reduction?

A temporary daily dosage of ZeoBac can help with nutrients but I would not recommend to do this more than 4 weeks.

3 weeks ago I added a bag of KZ aragonite. Before I add the aragonite I rinsed it well for a week, changing the RO water 2 times daily.
Before adding it I measured my PO4 at 0.04. One week later my PO4 was 0.2(!!!) with no ill effect on my corals.
I performed a 50% water change and one week after another 40% water change.
I also used seachem phosguard (half dose) changing it every 2 days.

Now my nutrients are
NO3: less than 2
PO4: 0.018

I'm also about to change my MH bulb and I just ordered an Iwasaki 50K.

Any thoughts?

Unusual, with a PO4 level of 0.2 mg you should for sure observe that your corals start to get darker tissue, might it just be a problem with your test ?

I do not have experience with the HQI bulb you plan to use but 50k is very blue which makes it IMO difficult to keep most kind of corals coloration.

PO4 level of 0.2 mg was for just a week. before they drop after the 50% water change. Corals are just fine after all. I test with hanna ultra low (phosphorus)

Actually iwasaki bulb is more like a 12-14K bulb in the eye and it is pretty good in PAR measures.
